TRACK MANIFOLD SANDING DEVICE.

Specification of Letters Patent.

Patented Feb. 14, 1911.

Application filed November 19, 1910. Serial N 0. 593,240..

To all whom 'it may concern:

Be it known that I, Jason W. WHITE, a citizen of the United States,residing at Pueblo, county of Pueblo, and State of Colorado, haveinvented certain new and useful Improvements in a Track Manifold SandingDevice, of which the following is a specification.

My invention relates to a manifold track sanding device and the objectsof my invention are, first,to provide a device for sanding the trackadapted preferably to electric motor cars; second,-to provide means fordoing the same so that the operator may sand one rail at a time and thusleave the other rail for free electric connection; and, third,to providean economical means for the sanding of the rails by the motorman fromhis station, including other purposes which will appear in thespecification.

I attain these objects by the mechanisms illustrated in the accompanyingdrawings in which,-

Figure 1 is a side elevation in broken section of the floor and truck ofa car showing the device attached; Fig. 2 is a top plan view of thedevice; Fig. 3 is an end view showing the operating lever and sprocketchain connection; Fig. 4; is an end view showing the means of operatingthe clutch;

Fig. 5 1s a side view showing the clutch and lever means; and Fig. 6 isa side view of the box and worm.

Similar numerals refer to similar throughout the several drawings.

Sand boxes 3 are adjusted in the floor 1 of the car so as to dischargein front of the trucks 1, and each box is provided with a false bottom 6slanting downwardly from the sides and ending toward the center andleaving a space therein for the operation above the lower edge of suchfalse bottom of apart of the worm 5 projecting above the false bottom.The shafts 10 and 4 are pro vided on each side underneath the car insuitable supports 2. Each of these shafts extends through the sand boxes3 on the parts respective sides and has attached in each box a worm 5.In each sand box is a discharge pipe 7. On the shaft 4: is the sprocketwheel and clutch 8 in which is turnable the shaft 4: as shown in Fig. 2.On the shaft 10 is the sprocket wheel 9. A sprocket chain 12 operatesoverthe wheels 8 and 9. The bracket 18 sustains the shaft 4: and beyondit on the end 11 of shaft 4: is attached the ratchet wheel 13. The lever15 is bifurcated at one end and is pivotally attached to the end 11 ofthe shaft 4, a part on each side of the ratchet wheel 13. Includedwithin the bifurcated portion is the pawl 14: pivotally attached at 1 1and operative on said ratchet wheel 13. The stem 16 is pivot-allyattached to lever 15 at 16 and the top is extended forming a shoulderfor operation with the foot above the car floor. A spiral spring 17 isprovided operative on the floor 1 and the shoulder of the stem 16. Theclutch 19 is placed on the shaft 4 provided with an element engaging aslot 19* in said shaft. The lever 20 is pivotally attached to the floor1 at 21 with fingers pivotally attached to the clutch 19 on a strapthereon at 25. The catch 22 is pivotally attached to the upright portionof the car 23 at 2i and is provided with slot means 22 to engage the topof the lever 20.

From practical experience it is ascertained that in the sanding oftracks for electric motor cars the sand tends to insulate the car wheelsfrom the rails, and decreases the effectiveness of the motors because ofthe sand acting as insulation and breaking the ground current. With mydevice when the sand boxes are all filled the motorman may oper; atethese boxes on the fixed shaft 4:, or on one side of the car, and theshaft 10 will be actuated; and when the sand in the boxes on shaft 4;has been exhausted, or for any other reason it is desired to use sandout of the boxes on shaft 10 on the other side of the car, by throwingthe lever 20 the clutch 19 will engage the clutch portion 8, and, as theratchet 19 is fixed to the shaft 4, it will operate, by means of thesprocket chain and-sprocket wheels, the shaft 10 and the sand from thatside'of the car may be used. By this means I provide a device operativewith the foot, and avoid the mess sity of the motorman using his hands,that may be otherwise engaged. The worm on the shafts in the bottom ofthe box extending above the false bottom brings the sand down into theworm and discharges it throu h the pipe in front of the trucks 1. It wilbe seen that my device attains the purpose of sanding only one rail at atime, or both rails at the same time, if desired; and that a sand boxand discharge pipe may be placed in front of each truck.

I claim, I In a i'nanlfold track sanding device of the characterdescribed comprising shafts atv tached to each side of and beneath thecar,

sand boxes in front of the trucks upon the car adjusted on said shaftsand provided With discharge pipes, a Worm attached to each shaftoperative in the bottom of each box, a false bottom in each boxadaptedto sprocket Wheel, lever means adapted for the 15. operation ofsaid clutch from the car floor, and a ratchet wheel attached to one ofsaid shafts constituting a drive shaft, a lever and pawl means adaptedto drive said ratchet Wheel provided With spring means and means forafoot operation thereof, all sub stantially as set forth.
